Bandera's Ice Cave and Volcano- We'd heard about this before, but missed it on our previous journeys. In a very volcanic area, the bottom of this cave always contains ice. Of course, we asked about why. It seems that the bottom of the cave is insulated from the earth temperature by several feet of lava and the top is also insulated from outside temperature swings. Cold air sinks into the cave and the water there remains frozen year round. Workers on the local railroad in the early 1900's used to keep their beer cold in the caves.
